Add support for pagination with Query API in Redis State Store

It seems that the paginated Query API is not being unit tested for Redis as - for example - is done here for Postgresql:
https://github.com/dapr/components-contrib/blob/c693061efb732c538d4c3a09e9936f8bc49c8726/common/component/postgresql/v1/postgresql_query_test.go#L36-L43

## Expected Behavior

Add a unit test that checks that pagination works with Query API on Redis State Store

## Actual Behavior

Query API on Redis State store seems not to be working correctly (at least on 1.12.4) when using "limit" and "token" parameters.

## Steps to Reproduce the Problem

Try Query API with pagination parameters (token and limit) on a Redis State Store anche check that the correct responses are received.

## Release Note

RELEASE NOTE: **FIX** Pagination management on Query API for Redis.

Start by comparing the Redis State Store Query API implementation and tests with common/component/postgresql/v1/postgresql_query_test.go, especially the pagination cases using limit and token. Reproduce the reported Query API request against Redis, then verify that paginated responses and continuation tokens are correct in a unit test.
